Sima Nan immediately realized what he was thinking? His treasures had been forcibly taken by the other party, yet now he actually felt grateful because they were returned. This was definitely not the reaction a demonic path expert like him should have!
Sima Nan was utterly terrified. He could no longer control his own thoughts. He suspected he had broken through to a false Mixed-origin mental state, or that he was still trapped in the illusion of the heart demon world rather than in the real world.
"I can only hope Master can provide a solution now!"
Sima Nan could only place his hopes on the Lord of the Demon Realm!
After giving Sima Nan his orders, Su Yuan's main body also began his assault on the Mixed-origin realm.
With the experience provided by Sima Nan, he no longer had any major doubts about breaking through to the Mixed-origin mental state.
The so-called Heart Demon Tribulation test wasn't about passively breaking through to the Mixed-origin mental state by passing the heart demon trial, but rather about transforming one's own mental state, which then allowed escape from the heart demon world.
Therefore, the heart demon world itself wasn't the key to breakthrough; what mattered was seeing through one's own mental barriers and achieving perfect unity.
But Su Yuan discovered a loophole!
The effect of the entry [Tempering Heart in Mortal Dust] stated that the more experiences he underwent, the more his talent, comprehension, and mental state would improve. Didn't this mean that the heart demon world was the best cultivation resource for him?As long as he experienced enough heart demon worlds, he could naturally elevate his mental state—it was completely automatic improvement, utterly unlike Sima Nan who needed to rely on his own comprehension and breakthroughs!
This felt like a bug!
With expectant emotions, Su Yuan launched his assault.
An invisible fluctuation activated the Heart Dao within the Immortal-Demon Realm Sea, causing rules to descend as the Mixed-origin Heart Demon Tribulation began!
Within the mental sea.
The Heavenly Demon Lord appeared out of nowhere, still dressed as black Su Yuan. Heavenly Demons themselves were formless—they could transform into countless shapes. No one knew what his true appearance looked like, and perhaps even he himself didn't know.
"Excellent! Your mental rules can already be considered properly established. If you can comprehend the Heart Dao next, you won't face major troubles in your mental cultivation in the future!"
The Heavenly Demon Lord looked satisfied at Su Yuan's mental sea. Over ninety percent of the mental sea was already completely under Su Yuan's control, just one step away from giving birth to a Mental Island!
Su Yuan smiled faintly: "Thank you for your guidance, Senior!"
The Heavenly Demon Lord's tone suddenly shifted: "But you are not the Demon Lord's successor! You deceived me!"
Su Yuan smiled faintly: "The demonic path has never been constrained by forms. Deception is fundamental cultivation for demonic practitioners. I wonder if Senior is satisfied with my deceptive methods?"
"Good, good. You suit my tastes, boy. But you still deceived me. I will increase the difficulty of your Heart Demon Tribulation by two times!" The Heavenly Demon Lord chuckled darkly.
He seemed to want to see a panicked, helpless expression on Su Yuan's face, just like Sima Nan's flustered demeanor that always amused the Heavenly Demon Lord whenever he saw it.
Instead, Su Yuan revealed a slight smile: "Senior, merely doubling the difficulty—isn't that looking down on me too much?"
The Heavenly Demon Lord was taken aback: "What do you mean?"
"My meaning is to increase the difficulty!" Su Yuan's gaze fixed on the Heavenly Demon Lord. "I think we can raise the Heart Demon Tribulation's difficulty by ten thousand times! That would be just about right!"
Hearing this, the Heavenly Demon Lord couldn't help but widen his eyes: "What did you just say? Ten thousand times? Are you sure you're not joking?"
Su Yuan looked puzzled: "Is ten thousand times not enough? Can we increase it further?"
The Heavenly Demon Lord's mouth twitched as he stared at Su Yuan: "This is the Mixed-origin Heart Tribulation! Although it's only a mental breakthrough, it's still a Mixed-origin level calamity. Once you fall, you'll face eternal damnation! This is no place for mischief! Even boasting needs to consider the occasion!"
Hearing this, Su Yuan said with serious expression: "Senior, this junior is not joking. I truly wish to increase the Heart Demon Tribulation's difficulty by ten thousand times. I've heard that the greater the difficulty of the Heart Demon Tribulation, the greater the benefits obtained afterward."
"What audacity!" The Heavenly Demon Lord's tone turned cold. "I originally thought you were a rare excellent seedling and successor in the demonic path. I never expected you to be such an arrogant, ignorant piece of trash! I misjudged you!"
The Heavenly Demon Lord couldn't hide his disappointment.
"Is Senior afraid? Or incapable?" Su Yuan actually tried to provoke him.
The Heavenly Demon Lord laughed in extreme anger: "Good, good, good! You're brainless enough, bold enough! You want to reach ten thousand times, right? How about increasing it to 129,600 times difficulty? Reaching the maximum difficulty of the Mixed-origin Heart Demon Tribulation?"
Hearing this, Su Yuan's eyes lit up: "Is that possible? So the maximum difficulty can be adjusted to 129,600 times? Then please make your move, Senior! I want this difficulty level for my Heart Demon Tribulation!"
The Heavenly Demon Lord sighed. He had thought he could scare Su Yuan off, but never expected this guy to become even more enthusiastic instead! This made the Heavenly Demon Lord completely unable to understand Su Yuan's thought process! This person was sick!
After confirming Su Yuan's foolish essence, the Heavenly Demon Lord drastically lowered his expectations for Su Yuan!
With a wave of his hand, the Heart Demon Tribulation power instantly erupted, sweeping through Su Yuan's entire mental sea.
Every single thought belonging to Su Yuan simultaneously connected to a heart demon world—1.296 billion heart demon worlds activated at once, causing Su Yuan's consciousness to simultaneously experience all 1.296 billion heart demon worlds!
In an instant, Su Yuan's consciousness sank into the heart demon worlds. In the blink of an eye, he lost his conscious awareness, completely immersed in these heart demon worlds beyond redemption.
Moreover, each immersion into one heart demon world would open the next layer of heart demon worlds, causing the cultivator's consciousness to sink into deeper heart demon worlds until they could never awaken again!
Su Yuan's countless consciousnesses instantly sank to the fiftieth layer of heart demon worlds. When multiplied by 1.296 billion divided heart demon worlds, the number had already become extremely enormous!
Seeing this, the Heavenly Demon Lord was extremely disappointed. He had thought such arrogance meant some reliance or super talent in mental aspects, but it turned out to be just an arrogant fool.
He shook his head, no longer planning to personally control this Mixed-origin Heart Demon Tribulation, leaving it to operate according to the Heart Demon Tribulation's own rules!
Meanwhile, within the God Realm Sea and Abyss Realm Sea.
Su Yuan's avatars here similarly maintained their fallen state.
But compared to the Immortal-Demon Realm Sea, their condition was clearly much better.
These avatars could even forcibly awaken themselves.
This was something Su Yuan had anticipated from the beginning—the so-called Heart Demon Tribulation couldn't directly affect avatars in another realm sea.
Once Su Yuan's main body in the Immortal-Demon Realm Sea truly encountered an accident, Su Yuan's main consciousness could reform in other realm seas.
Su Yuan's main consciousness had already entered the 100,000th layer of heart demon worlds.
He hadn't expected to sink so deep into the heart demon worlds.
Fortunately, through his consciousness in other realm seas, Su Yuan clearly realized he was within heart demon worlds rather than the real world.
But Su Yuan only recognized this fact—he fundamentally couldn't see through this world's true appearance.
Everything he perceived, all the power gained through cultivation—everything felt completely real!
However, there was one flaw. Su Yuan summoned his system panel. The system panel's data didn't change with the heart demon world's transformations but instead displayed what should appear in the real world.
The mere Heart Demon Tribulation world simply couldn't affect the system panel.
But the [Tempering Heart in Mortal Dust] entry remained brightly lit the entire time. His talent, comprehension, and mental state were truly rapidly improving!
Across hundreds of millions of worlds, Su Yuan simultaneously experienced hundreds of millions of worlds. The richness of his experiences allowed his entry effect to reach unimaginable levels.
Especially in this Heart Demon Tribulation world, time seemed false—experiencing a complete lifetime, even ten billion Yuan Assemblies seemed to unfold in just a single day!
No wonder the Heart Dao required coordination with the Time Law—the heart demon world effect was too excellent!
In some heart demon worlds, Su Yuan sat high upon clouds as the Lord of the Immortal Realm, ruling over countless cultivators, making even mighty experts bow their noble heads!
He controlled fate, divided yin and yang—everything moved according to his will!
In some heart demon worlds, Su Yuan was merely a swimming fish, his brief life lasting only a few hours before being caught ashore, sold at market, and finally slaughtered by sharp blades!
Deity, human, immortal, livestock, bird, beast, insect, fish, spiritual being.
Su Yuan transformed into countless forms, experienced countless lives. His experiences became increasingly rich and diverse through these endless heart demon worlds.
His mental state rapidly rose to Mixed-origin Golden Immortal perfection during this process and quietly completed an epic transformation.
Within the mental ocean, a Mixed-origin unified heart core condensed out of nowhere. At the center of the mental sea, a Mental Island slowly rose, representing how Su Yuan's mental state had transformed into the Mixed-origin mental state at this moment.
But Su Yuan didn't awaken from the heart demon worlds. He continued accepting the heart demon worlds' immersion.
His mental will continued to rapidly improve. Su Yuan greatly enjoyed this process, completely unwilling to stop.
Nothing in the world could compare to this cultivation environment—it was truly exhilarating!
Only a few months had passed in the external world.
But trillions of heart demon worlds had experienced countless ages.
The Time Law was displayed to perfection within this Heart Demon Tribulation.
Su Yuan's mental cultivation astonishingly rose from early Mixed-origin Great Luo Golden Immortal to mid-stage Mixed-origin Great Luo Golden Immortal!
This kind of improvement could be called earth-shattering, unprecedented throughout eternity!
Mixed-origin Great Luo Golden Immortals were already mighty experts. Improving even a minor realm required accumulating time equivalent to a Calamity Tribulation—that is, 6.4 billion Yuan Assemblies of time!
Yet Su Yuan actually managed to successfully overtake on the curve through the Heart Demon Tribulation and the [Tempering Heart in Mortal Dust] entry, elevating his mental cultivation to the incredible mid-stage Mixed-origin Great Luo Golden Immortal!
